Topic: Is the SL1 sensor an improvement? (Read 8833 times)

DPReview published some JPEGs from a pre-release camera. Still, I can't do this with my T2i. Here I've pushed blacks that were in the neighborhood of 8 counts up to the neighborhood of 140 counts. I see no sign of banding and very little noise.

What do you think? Better noise processing? Black point clipping? Or a genuine reduction of read noise? Raw images will settle this, but I haven't seen any yet.

Its at least two generations newer than your T2i. Some seem to think that the number of pixels defines a sensor generation. It doesn't. This is supposedly a second generation Hybrid sensor.

As far as IQ, at low ISO's you are almost certainly not going to notice any difference. Improvements to sensors are most noticible by the reduced noise at high ISP's, or, in this case, by better hybrid autofocus.

The bottom line is that its a improvement for focusing in the live mode, and probably has a bit lower noise at high ISO'sin jpeg mode due to the new Digic 5. Certainly no big difference unless you want autofocus while taking video.

There's a huge difference between 33.1e- and 2.7e- when you have to push the shadows really hard. I don't run into base ISO dynamic range problems a lot, but I wouldn't mind Canon getting competitive here so that when I did I didn't struggle with the noise produced.

Canon's sensors have always been superior or competitive at high ISO where read noise drops dramatically and performance is dictated by Quantum Efficiency where the 5DIII and D800 are nearly the same at around 50%.

I'm also very curious about whether any low ISO FPN has improved in this generation.However, OOC jpg is not a great indicator, even jpgs from my bandy 7d looked good, raw held the real problem.

I can bide my time... waiting for something truly good to come along from Canon, as I already have truly good from other mfrs to use in the meantime.Heck, i even sold my EF 70-200 f/2.8 L v2 the other day, since it doesn't fit on my d800...

It has to be an improvement.... a new version of focusing on the sensor for live view... and a lot more computing power that can hopefully run a better/faster algorithm for determining focus.

I regard focusing ability as the most important aspect of a camera. I've said it before and I'll say it again, megapixels, dynamic range, ISO capability, and great glass don't matter if the shot is out of focus.

As far as IQ, at low ISO's you are almost certainly not going to notice any difference.

Not true.

"DPReview published some JPEGs from a pre-release camera. Still, I can't do this with my T2i. Here I've pushed blacks that were in the neighborhood of 8 counts up to the neighborhood of 140 counts. I see no sign of banding and very little noise.

It is true, he asked how it would compare to his T2i, not a D800. A D800 or Nikon was not mentioned by the OP!Its not going to be much different from his T2i.

I appreciate the input of many on this forum... but what I think Mt Spokane and Neuro have missed in this, is that Lee Jay IS the OP. I am following Lee Jay's line of thinking here....

At the end of the day I hope there is improvement at both Low ISO and High ISO ... ie less noise, low banding, etc.

I appreciate using my 7D and 350D cameras along with a host of lenses & many accessories to capture quality photos, and share with friends.

I can lift the shadows of my 7D at ISO 400 or greater by quite a bit and not experience banding noise. Problem is, I have already lost ANOTHER stop of DR by ISO 400 relative to ISO 100/200, so that really isn't saying much.

If the sample GIF shots are ISO 100, I have to say...that looks fairly impressive. I would have expected banding noise to show up in an ISO 100 shot lifted that much.
